HUMAN PHYSIOLOGY

 HUMAN PHYSIOLOGY

The study of functioning of organs and organ systems is called human physiology. It is the science of studying human mechanical, physical and biochemical functions, and is the basis of modern medicine. As a discipline, it connects science, medicine, and health, and creates a framework to understand how the human body adapts to stress, physical activity, and disease. The term human physiology is derived from the Greek word (physics=nature ; logia=study). 

The human physiology

Various types of evolutionary organs and their well-coordinated functions make the phenomena of life possible. The heart’s role as an emotion-controlled pumping organ is surprising. The oxygen binding and dissociation ability of blood pigments, the cascading effect of a very small amount of hormones at the molecular boundary, the nerve conduction process, the brain’s analytical and memory capabilities, and the general visual perception of the eyes are all natural processes towards the simple life. 

The complex and genetically oriented mechanism for the production and reproduction of sex cells to simplify the process of sexual reproduction is amazing. Reproductive strategies are geared towards high-precision and purpose-oriented social, environmental and futuristic motives.

Physiology tests how the organs and systems in the body work, how they communicate, and how they work together to create favourable conditions for survival.

BRANCHES

Cell physiology

Cell physiology is the study of biology, which involves all normal functions that occur in an organism. In the context of human physiology, the term cell physiology is generally particularly applicable to the physiology of membrane transport, neuronal transmission, and (less frequently) muscle contraction. Generally speaking, these include the digestion of food, blood circulation, and muscle contraction. 

Defense physiology

Changes in response to potential threats, such as preparing for a fight or flight response. When the body performs a “fight or flight” response or a stress response, the nervous system activates, coordinates, and directs specific changes in bodily functions (physiology) and is ready to meet threats.

Evolutionary physiology

Evolutionary physiology

Evolutionary physiology is the study of biological evolution in the physiological structure and process; that is to say, in the historical process of the population, the way in which the functional characteristics of the individuals in the organism population respond to natural selection.  It is a branch of evolutionary biology and physiology. Professionals in this field come from a variety of backgrounds, including physiology, evolutionary biology, ecology, and genetics.

Exercise physiology

Exercise physiology

As its name suggests, it is a study of the physiology of physical exercise. This includes studies on bioenergetics, biochemistry, cardiopulmonary function, biomechanics, hematology, skeletal muscle physiology, neuroendocrine function, and nervous system function.

Systems physiology

System physiology is a comprehensive discipline. It combines experiments, calculations, and theoretical research to promote our understanding of the physiology of humans and other organisms. In other words, systems physiology is systems biology with a point of view focused on physiology (that is, function).
